MULTIEPLE-SPOOL HOLDER.

Application filed. August 12, 1922.

T 0 (a l whom it may concern:

Be it known that I, MILTON ZUBER, a citizen of the United States, andresident of New York city, in the county of New York and State of NewYork, have invented certain new and useful. Improvements inMultiple-Spool Holders, of which the following is a specification.

My present invention relates primarily to multiple spool holders, andalthough it has its preferred application in the textile industry forholding a plurality of spools of thread in convenient position againstloss and for convenient access at will to the thread of any selectedspool, many of the preferred features are applicable in any relationwhere access is desired at will to any one of a plurality of reels,spools or other magazines of thread, wire or other material.

It is an object of the invention to provide a spool holder ofparticularly simple rugged and inexpensive construction for supportingspools without danger of entangling the threads or other materialthereon and which shall permit access readily and conveniently to anyselected spool.

Another object is to provide a holder of the above type which shall besuited to mounting any desired number of spools in position and in whichthe spools can be readily removed or replaced when exhausted.

In a preferred embodiment, the spool holder comprises a built upconstruction, including a plurality of spool. support bracket armsmounted upon a support, the spool held at one end by each arm beingmaintained in position by the coaction of one of the other arms againstremoval when the device is locked.

In a preferred specific embodiment, the bracket arm members aretelescoped over a cylindrical support rod and successive arms are keyedwith respect to each other, the arms extending outward from the supportrod in a plurality of groups, each group in a common plane, thetelescoping bracket portions for each group constituting spacers betweensuccessive arms in each other group.

In a preferred inexpensive construction, the support rod is a simplevertical tube, the bracket members are composed of T fittings telescopedover said tube and the bracket arms are pipe elements fitting into thestems of the T fittings and flattened at their outer ends for support ofthe spools. A look is Serial No. 581,311.

provided above the uppermost of the bracketarms to prevent separation ofthe keyed connection between successive arms, so that the spool memberswill all be locked in position and may be released upon opening of thelock member to raise any bracket arm for separation thereof with respectto the associated spool therebelow which can then be removed forreplacement.

In the accompanying drawings in which is shown one of various possibleembodiments of the several. features of the invention,

Fig. 1 is a side elevation with parts broken away of a preferredembodiment of the invention, shown in section, and:

Fig. 2 is a plan view thereof.

Referring now to the drawings, I have shown a spool holder comprising abase, pedestal or support 1 preferably. provided with lugs 2 by which itmay be screwed to a table, bench or other support. Preferably threadedinto the upper end of the base is a support tube or rod 3. In thepreferred specific embodiment, a plurality of fittings 1, 5, 6 and 7,10, 11 and 12, are telescoped over the support rod, each fitting havinga key 8 integral therewith in the lower edge thereof fitting into acorresponding keyway 9 in the upper edge of the adjacent fittingimmediately therebelow. Fittings 4, 5, 6 and 7 in the specificembodiment are shown as ordinary T fittings, within the stems 13 ofwhich are threaded and secured short lengths of pipe 14 flattened as at15 near the outer ends thereof to constitute spool supporting platforms.The telescoped fitting 5 which extends toward the left together with thecollar fitting 10 constitute a spacer between fittings 4 and 6 extendingtoward the right, to afford the required gap between the free ends ofarms 14 and 14 for accommodating a spool as at 16. Similarly thetelescoped fitting 6 with collar fitting 10 constitute a spacer betweenfittings 5 and 7 for accommodating a spool (not shown) therebetween.Each spool. is preferably mounted upon a in, axle or rod 17 having ahead 18 pressed lnto a corresponding aperture 19 on the fiattenedportion 15 of the arm therebelow and extends upward therefrom, the upperfree tapered end 20 of each pin extending in the assembled constructioninto a corresponding depression 21 in the lower end of the in headimmediately thereabove, Spool pins of the type described, it will beseen, are secured into the arms of fittings 4, 5, 6 and 7 in thespecific embodiment shown.

A special crown fitting 12 is telesooped over the upper end of the rodand has a key connection 22 with the spacer collar 11 immediatelytherebelow. Crown fitting 12 has pipe stem. extensions 23 similar tothose heretofore described, affording sockets 24 at their endsfor-coaction with the upper ends of the spool pins 17.

The device described is releasably locked by a lock cap 25 telescopedover the free end of the support rod above the crown fitting 12, thecross pin 26 through the support rod extending into an elongated slot 27in the cap to limit the elevation thereof. The cap is normally retainedin its lowermost or locked position by a spring latch. member 28 fittinginto corresponding notches 29 in the inner wall of the support tube nearthe upper end thereof, said latches being releasable by means of a key(not shown) insertable through a keyhole 30.

It will be seen that the multiple spool support described is ofparticularly simple and inexpensive construction. The keys and 'keywaysare readily produced by a simple 'milling operation upon standard Tfittings and. theflattening of the spool supporting rod eirtensions isreadily effected by means of a punch press operation. It will be readily seen that by inversion of a T fitting for coaction of its keys witha corresponding keywayof an adjacent identical fitting. the arms of saidtwo fittings will extend as shown at 4:, 5 in opposite directions fromthe support rod, as desired.

The spool holder, it will be seen, is a builtup construction assembledby telescoping the successive identical T fittings and spacer collarsover the support rod, applying the locking cap and as a final operation,applying the lock pin 26 in position. To charge the multiple spoolholder, it is merely necessary to release the latch 28, elevate the capto the limit allowed by the slot 26 which permits elevation of any oneof the fittings to release its keyway connection to those therebelow, topermit ready displacement thereof about the support rod 3 as an axis toexpose the upper end of the spool anchoring pin immediately :therebelow.By this means, it will be seen that a spool can read ily he slipped overeach or any required number of the support axles, whereupon, the bracketarm immediately thereabove can be restoredto its original position andwhen they have all been restored, the cap 25 can be snapped back tolocked position. If all of the keys are not in proper coaction withtheir keyways the-locking cap is in .a posit1on higher than raisedlocking position. It

will therefore be seen that the locking cap cannot be snapped tolocking'position until.

until lock 28 is opened by an authorized person in possession of a key.

In use, the operator grasps the thread on any selected spool and drawsthereon in the usual manner for sewing either by machine or by hand.Upon drawing on the thread,

the tension thereon will effect rotation of the entire assembly ofbracket, support arms and spools about the spool support 3 as an axis tobring the selected spool into most convenient position relative to theoperator, without danger of entangling with respect to the threads onthe other spools,. which maintain their position relative to theselected spool.

In order to prevent spinning of any spool about its axle, it ispreferred to provide dished springs 31 encircling axle pins 17, to exertfriction or braking force upon" each spool, by forcing it against thebracket arin immediately thereabove. By this operation, friction will beexerted upon the spool, such that when the tension is applied to thethread thereof, the spool will firstbe drawn. together with the entireassembly of sleeve fittings and projecting arms to the position in whichthe tensed thread is in the plane of the support rod. By reason of thebraking effect of springs 31. tension suddenly applied to the threadwill not cause spinning of the spool about the axle and will avoid anyconsequent danger of entangling the thread. y

When a spool is to be replaced after exhaustion thereof or forsubstitution of different type or color of thread. the opera tor opensthe look 28, raises the cap 25, raises the arm 14 immediately above theexhausted spool. thereby releasing the free end of the correspondingspool support axle 17, and after laterally shifting the arm about thesupport rod. he can remove the spool from its pin. The operation of replacement, resetting and locking the'devioe will. be obvious from theforegoing.

The embodiment shown in the drawings is merely a simple preferred formof the in vention. It will, of course, be understood that by providingadditional fittings and a longer support rod, the spool holder may be ibuilt up to any elevation desired. It will be moreover understood thatthe bracket arms may be extended in three or more planes atcorresponding angles. It will also be apparent that, if desired. theentire group of bracket arms and their telescoping portions may beformed as a single integral sleeve about the support rod or may beformed in rious objects of the invention and is well suited to meetrequirements of practical use.

As many changes could be made in the above construction and manyapparently widely different embodiments of this inven tion could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and not in a limiting sense.
